LYTHRACE.E. 
Ammannia Senegalensis. 
Lamarck, Eucyclopedie, t. 77, f. 2. 
Port Moresby ; Goldie. For synonymy see Hiern in Oliver’s Flora of 
Trop. Africa, ii. 477. Closely allied to A. latifolia (L. Sp. 119), which 
also as an Indian plant is mentioned by Grisebach (Flora of British 
West India, 270). 
Ammannia baccifera.

BEGONIACE^. 
Begonia Malabarica. 
Lamarck, Encycl. Method, i. 393. 
Fly-River ; D’ Albertis. 
The almost glabrous less denticulated leaves, the smallness of the 
flowers and the truncate wings of the fruit separate this species from B. 
dipetala (Grab, in Hook. Bot. Magaz. t. 2849), as well pointed out by 
Alph. de Candolle (Prodr. xv. 391-392). The placentas of our plant 
are however consisting of two plates, and this character would bring 
the Papuan species to B. fallax (A. de Cand. Prodr. xv. 329), if the 
flowers were petaliferous and the base of the fruit more acute. 
Begonia spilotophylla. 
Leaves from a semicordate base oblique oblong-lanceolate, long- 
acuminate, minutely denticulate, glabrous, white- or pale-spotted ; 
stipules subulate-linear; peduncules few-flowered; sepals 2, small, orbi- 
cular; petals none ; stamensarising from the depressed torus; anthers 
about as long as the filaments, their connective not produced beyond 
the cells; fruit-wings three, shorter than the au'is, not extending to the 
pyramidal summit of the fruit ; placentas bilaminate; seeds furrowed. 
Near the Fly-Rivei' ; D’Albeiiis. 
Leaves 5-9 inches long, mostly (so fas as known) from 1|~3 inches 
broad. Petioles 1-1 1 inch long. Stipules 3-4 lines long. Peduncles 
of the only flowering specimen seen b}^ me about 1 inch long. Second- 
ary peduncles and pedicels nearly as long. Sepals measuring about ^ of 
an inch. Anthers at the summit rounded-blunt. Styles not seen. Cap-
